nl50 - too agressive with top two paires?

[No_Match]

Villain 9/9/oo, 80 hands, no reads.
I played the hand pretty automatic way but now I wonder, do I really ahead of enough villain's holdings? Maybe I should fold to AI?
Second question is perflop. It seems to me now, that raising would be much better if I want to play this hand profitably. Thoughts?

this is fine. i don't think you have any FE PF and this opponent's PF calling range crushes yours. also, if you hit, it'll be very hard to extract being OOP. might as well keep the pot small.

this is often enough an overpair that failed to LRR PF, JT, sometimes AJ, etc. you played it fine.
